Abstract

(57) [Abstract] [Purpose] The present invention relates to a fitting device made of synthetic resin. [Structure] A reverse movement preventing claw (1) is provided on the upper side of the fitting receiving port (5), and after the fitting protrusion head (3) is inserted, the backward movement preventing claw (1) is used. I made it so that I could not reverse or pull out.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fitting device made of synthetic resin or the like.

[0002]

[Prior art]

 Conventionally, this type of fitting device made of synthetic resin or the like allows the fitting protrusion (7) to be inserted into the rim of the receiving opening (6) while giving a crack at the time of fitting, so that the receiving opening is loose. Therefore, there is a drawback that the fitting protrusion (7) can be easily pulled out even after the fitting.

[0003]

[Problems to be solved by the device]

 Except for its drawbacks, the present invention fits lightly and smoothly at the time of fitting, and after fitting, the reverse movement preventing claw (1) installed on the upper side of the fitting receiving port (5) acts, An object is to provide a fitting device in which the mating stem (3) cannot be reversed or pulled out.

[0004]

[Means for solving the problem]

 The solution means will be described with reference to the drawings. (A) The fitting receiving port (5) has a straight receiving hole without a taper shape (5), and the wall thickness around the hole is made slightly thick so that it is difficult to tear. (B) One or a plurality of reverse movement preventing claws (1) are provided on the upper side of the fitting receiving port (5). (C) The inner diameter (A) of the fitting receiving port (5) is Design a little larger than the outer diameter (B) of the head of the stem (3). (D) After the fitting, the backward movement preventing claw (1) is circularly surrounded by the protection wall (2) so that it cannot be directly touched from the outside. ), No longer able to abuse. The present invention has the structure as described above, and when it is made, it is made of a slightly hard and elastic synthetic resin, that is, polypropylene or polyacetal resin, for example.

[0005]

[Action]

 Since the present invention has the structure as described above, when this is used, when the fitting protrusion head (3) is inserted into the fitting receptacle (5), the upper side of the fitting receptacle (5) is inserted. The anti-reverse claw (1) in Figure 1 is pushed upward to pass, and when it has finished passing, the anti-reverse claw (1) is crimped to the fitting protrusion leg (4) by the elasticity of the synthetic resin. Ru

[FIG. 3] (1) When the fitting protrusions (3) and (4) that have been tightly fitted in this way are pulled backward and pulled out, the reverse movement preventing claw (1) is placed within the diameter of the fitting receiving port (5). Since it is rolled up and the fitting receiving port (5) is closed, the fitting projection head (3) cannot be moved backward and pulled out.

[0006]

【Example】

 In carrying out the present invention, one end of a cord-shaped body is connected to a male type of a fitting device, and the other end is attached to a female type of a fitting device to be used as a closure.

[Figure 6]
Also, both ends of the cord-shaped main body are bifurcated, and one pair of male and female fitting devices are attached to the ends thereof to be used as a strap.

FIG. 7 is also available.

[0007]

[Effect of device]

 As described above, the insertion and fitting can be done lightly, but once the fitting is completed, it cannot be pulled out backwards.Therefore, a fitting device that is effective for sealing sealing tools and sealing tools. Is.

Claims (1)

[Scope of utility model registration request] 1. In a fitting device, a reverse movement preventing claw (1) is provided on an upper side portion of a fitting receiving port (5) so that the fitting protrusion (3) is reversely moved or pulled after being inserted and fitted. A fitting device that does not come off.
